function J = computeCost(X, y, theta)
%COMPUTECOST Compute cost for linear regression
%   J = COMPUTECOST(X, y, theta) computes the cost of using theta as the
%   parameter for linear regression to fit the data points in X and y

% Initialize some useful values
m = length(y); % number of training examples

% You need to return the following variables correctly 
J = 0;

% ====================== YOUR CODE HERE ======================
% Instructions: Compute the cost of a particular choice of theta
%               You should set J to the cost.


h = theta' * X';
# disp(size(h));
# disp("(h - y).^2---------");
# disp((h - y').^2)
J = sum((h - y').^2)/(m*2);
# disp("J---------");
# disp(J);
